Specification of Letters Patent.

Patented March 19, 1907.

Application filed December 1,1905. Serial No. 289,838.

provide a source of power mounted on the threshing machine and having operative connections with the cylinder and other working parts of the machine and also with the carrying or traction wheels.

The invention consists generally in various constructions and combinations, all as hereinafter described, and particularly pointed out in the claim.

In the accompanying drawings, forming part of this specification, Figure 1 is a plan view illustrating the application of the source of power or. driving means to the tractionwheels. Fig. 2 is a side elevation of one end of the machine. Fig. 3 is a sectional view on the line y y of Fig. 2.

In the drawing, 2 represents a suitable frame havin a forward axle 3 and wheels 4, provided wit a steering mechanism 5, operated through a rod 6 and hand-wheel '7 and corresponding substantially to the steering ap aratu's' of an automobile, and a rear axle 8, aving traction-wheels 9. An engine 10, preferab y of the gasolene four-cylinder type, is mounted on the forward end of the frame and is connected with a multi le-crank shaft 11, having fly-wheels 12. A oose ulley 13 is provided on one end of said s aft and adapted to be locked on the shaft by a clutch machine and connected with said clutch at one end, and a rod 16 is attached-to the other end of said lever and extends'across the machine-frame and is attached to one arm of a bell-crank 17, the other arm of which being connected to a rod 18, which extends to an operating-lever 19. When this lever is moved back and forth, the bell-crank 17 will be rocked and the lever 15 o erated tolock the pulley 13 on the crank-s aft .or release the same. A belt (indicated by dotted lines in Fig. 2) connects'the pulley 13 with the threshing-cylinder, and from which the other threshing mechanism,may be driven in the usual way, itnotj'being necessary to illusftrate'the belt connections in this case. Y On the other end of the crank-shaft 11 from the pulley 13 is a clutch 20, one member thereof carrying a pinion 21 and being loose on the crank-shaft. The other member of the clutch is s'plined on the shaft in the usual way and moved back and forth toward or from the loosely-mounted member by means of the lever 22, connected by a rod 23 with one arm of. the bell-crank'24, which in turn is connected by a rod 25 with an operating-lever 26. A driving-shaft 27 is mount.-

- ed on the machine-frame at right angles sub stantially to the crank-shaft, and beveled gears 28 are s lined on said shaft on each side of the pinion 21. A yoke 29'has forked ends upon each side of said gears to fit into grooves 30 in the hubs thereof and allow them to be moved back and forth on the drive-shaft.

'An operating-lever 31 is pivoted at its lower end on the machine-frame and con-' nected by a rod 32 with the oke 29. A plate 31 is preferably mounte on the machine-frame, having notches to receive a locking-latch 31" on said locking-lever and by means of which the gears can be locked in osition to drive the machine forward or ackward, as preferred. Suitable quadrants 32' are provided for the other levers to receive the locking-latches in the usual wayf By means 'of these levers, heretofore described, the operator can move the gears 28 forward or back to operate the-machine inl either direction and whenever desired can lock the pulley 13 on the crank-shaft to drive the threshin mechanism. The rear end of the driving-s aft 27 is provided with a pinion 33, arranged to engage the teeth of a propulsion of the machine in the desired direction.

I do not wish in this application to be con- I 1o 5 fined to the location of t e engine or source of power on the machine-frame, as it may be placed at the rear instead of the forward end, 1f preferred. In various wa s the details of construction may be mo ed Without departing from my invention.

j This invention is a plicable to other lines of agricultural 'inac f ery,. such as com- IIO shellers and clover-hullers, as well as to I threshing-machines;

I claim as my invention,

The combination, with a threshing-machine frame having forward and rear axles and traction-wheels, of adriving-shaft having sliding gears at its forward end and a fixed pinion at its rear end, a transverse shaft mounted in said frame, near the rear wheels and having ini'ons meshing with gears mounted on tli gear mounted on said transverse shaft and engaging the fixed pinion on said driving- I shaft, anengine mounted on said. frameand having a crank-shaft and flywheels, a loose pulley mounted on one end of said crankshaft and belted" to the threshing-cylinder, a

e rear axle, a compensating sezvae locking-clutch for said loose pulley, a second clutch mounted on said crank-shaft and having a pinion adapted to engage one or the other of said sliding gears according to their position on said driving-shaft, levers having operative connections with said elutches,'a
